The field of public health preparedness encompasses many important areas, including preparedness programs in responding to bioterrorism, mass casualties, chemical emergencies, natural disasters, radiation emergencies, and infectious disease outbreaks. The strength of these programs lies in its shared mission to strengthen public health training and workforce development, especially in the areas with limited access to scientific literature and the Internet. The majority of public health emergencies can be prevented and/or mitigated with improved access to scientific literature, open access software, and open access educational modules. Getting information to the right people at the right time is essential. Today, access to information usually implies access to a reliable computer. Contrary to some myths, one does not need the most expensive computer and fastest Internet connection in order to access and utilize high quality educational materials. Computers that often get disposed in U.S. and other developed countries can be used just as effectively as the latest and greatest machines for access to the information. The key to improved access to information is a functional computer. The key to functional computer is oftentimes not hardware, but its software, configuration, user awareness, and attitude towards computer usage. This chapter will discuss how to protect and tune a computer for optimal performance without needing to buy a new one. It will also outline how older machines could be effectively used to access public health preparedness information online.
